1. Oxidative chloro- phosphorylation reaction of nitrile-butadiene rubber (NBR) and characterizationby the methodof infrared spectroscopy study. Baku State University Master of Chemistry Balayeva Ofeliya E-mail: Ofeliya1989@inbox.ru *This research work were carried out by headed A.A.Azizov with the participation of R.M.Alosmanov and İ.A.Buniatzade.

2. Abstract Special-purpose nitrile butadiene rubber(NBR) chloro-phosphorylate with the participation of oxygen. Polymer obtained were characterized by infrared spectroscopy.

3. 1. Introduction Most polymer materials are good dielectrics with stable physical and chemical properties. Modification of polymers with various inorganic fillers is used for altering their mechanical, electric, and other operational properties . Nano-sized metals have different properties from bulk metals originating from nanocrystals size. Nanocrystals measure a few nanometers containing few hundred atoms. In this way, nanomaterials show unique properties (electronic, magnetic, structural) depending on nano-size structure.

4. ACRYLONITRILE-BUTADIENE RUBBER (NBR) Properties and Applications Nitrile butadiene rubber includes of special-purpose synthetic rubbers. Nitrile butadiene rubber (NBR) prepare from the radical polymerization of butadiene-1,3 with acrylic acid in emulsified water. In depends the amount of acrylonitrile there are NBR-18, NBR -26, NBR-110 branded types of butadiene nitrile rubber. We have used NBR-26.

5. The molecular structure of (BNR)

6. Properties of (NBR) The molecular weight: -200-300 ths.mol/q density : 0,943-0,986 g /ml glass transition temperature : -32 - (-55) ° C. The structure : amorphous. With increasing of the amount of nitrile groups in molecules of nitrile- butadiene rubber, the solution decreases, glass transition temperature and the density increases. The rubber of NBR-26 is widely used for production oil-gasoline-resistant rubbers and electric conductor rubbers.

7. 2.Experimental Part For solution of nitrile- butadiene rubber we used chloroform (CHCl3). Rubber was solved in chloroform. For oxidative chloro phosphorylation of nitrile butadiene rubber (NBR) PCl3 has been added to over the intervals. After filtration the polymer was washed in solution of acid and base and distillated water. Then polymer was dried at room temperature.

8. 3.The characterization by the method of Infrared spectroscopy study of the phosphochlorizated NBR polymer. The characterizationof special-purpose synthetic nitrile- butadiene rubber by the method of infrared spectroscopy study is more effective method.
